Definitions
- the present invention relates to improvements in a control device for an air conditioner for use in an automotive vehicle.
- JP-A-63-90420 discloses a conventional air conditioner control device for an automotive vehicle.
- This air conditioner control device is arranged such that the operation of the air conditioner is stopped during an acceleration of the automotive vehicle and restarted according to the up-shift operation of an automatic transmission, in order to prevent the acceleration performance from being lowered by the operation of a compressor of the air conditioner. Accordingly, the operation of the compressor is stopped only during the acceleration period.
- control device provides a detector for detecting input rotation speed of the automatic transmission through the rotation speed of the turbine shaft of a torque converter in order to detect the finish of the up-shift operation. This increases a production cost of the control device. Additionally, the reliability of the control device is effected by the sensor and automatic transmission.
- the above object is achieved by an arrangement wherein a compressor of an air conditioner is connected with compressor stopping means and compressor restarting means as shown in FIG. 1.
- the compressor is stopped by the compressor stopping means when an automotive vehicle is in an accelerating condition and restarted by the compressor restarting means when a proper time is elapsed after a stopping of compressor time and a start of the shifting operation in an automatic transmission.
- a first aspect of the present invention resides in a control device of an air conditioner for an automotive vehicle.
- the air conditioner has a compressor for generating a refrigerating cycle.
- the automotive vehicle has an internal combustion engine with an automatic transmission.
- the control device comprises a compressor stopping means which stops the compressor during an acceleration of the automotive vehicle and a compressor starting means which restarts the compressor when a first predetermined time has elapsed from the stopping of the compressor and a second predetermined time has elapsed from judgment of shifting of the automatic transmission.
- a second aspect of the present invention is deemed to comprise a method of controlling a compressor of an air conditioner for an automotive vehicle which has an internal combustion engine with an automatic transmission.
- the method featuring the steps of: stopping the compressor during an acceleration of the automotive vehicle; and starting the compressor when a first predetermined time has elapsed from the stopping of the compressor and when a second predetermined time has elapsed from a start of shifting of the automatic transmission.
- FIG. 1 is a block diagram which shows a conceptual structure of an air conditioner control device according to the present invention
- FIG. 2 is an embodiment of an air conditioner control device according to the present invention.
- FIG. 3 is a flow chart which shows a control manner of an air-conditioner control device of FIG. 2;
- FIG. 4 is another flow chart relating to the flow chart of FIG. 3.
- FIG. 2 to 4 there is shown an embodiment of an air conditioner control device according to the present invention.
- an automatic transmission 12 which is constituted by a torque converter, a shifting gear mechanism and a hydraulic circuit, is connected with an internal combustion engine 10.
- An air conditioner 50 for conditioning a passenger compartment of an automotive vehicle comprises a compressor 14, a condenser (not shown), an expansion valve (not shown) and an evaporator (not shown) which make a refrigerating cycle.
- the air conditioner 50 provides cool air into a passenger compartment of the automotive vehicle by means of its refrigeration system.
- the compressor 14 of the air conditioner 50 is connected with the internal combustion engine 10 through pulleys and a belt to be operated according to the operation of the internal combustion engine 10.
- the automatic transmission 12 is electrically connected with an automatic transmission controller 16 through which the operation of the automatic transmission 12 is controlled.
- the compressor 14 is electrically connected with and controlled by an air conditioner controller 18.
- the automatic transmission controller 16 is arranged to output signals indicative of judgment of shifting, accelerating time and the like to the air conditioner controller 18. Furthermore, a signal indicative of the switching of the air conditioner is outputted from an air conditioner switch 20 to the air conditioner controller 18.
- the air conditioner switch 20 is manually turned on and off by a passenger of the automotive vehicle.
- the air conditioner controller 18 controls the on-off switching operation of the compressor 14 by controlling a magnetic clutch (not shown) installed in the compressor 14 according to the signals from the automatic transmission controller 16 and the air conditioner switch.
- a program shown by this flow chart is repeatedly implemented from a time that an ignition switch of the automotive vehicle turned on.
- a step S102 it is judged whether the air conditioner switch 20 is turned on or not.
- the program proceeds to a step S120 wherein the compressor 14 is turned off.
- the program proceeds to a step S104 wherein it is judged whether the automotive vehicle is in an accelerating condition or not.
- Such a judgment in the step S104 is implemented on the basis of a throttle opening and a shift-position in the automatic transmission 12. This information of the engine 10 and the automatic transmission 12 is sent through the automatic transmission controller 16 to the air conditioner controller 18.
- the program proceeds from the step S104 to a step S106 wherein a flag F1 indicative of a predetermined accelerating condition of the automotive vehicle is set at 0.
- the program proceeds to a step S108 wherein it is judged whether the flag F1 is 1 or not.
- the program proceeds to a step S109 wherein the compressor 14 is turned on.
- the program proceeds to a step S112 wherein it is judged whether a flag F2 is 1 or not.
- the program proceeds to a step S114.
- a time T of a time counter is incremented by 1 (T ⁇ T+1).
- a step S116 it is judged whether the time T is larger than the predetermined time period T0 or not.
- the program proceeds to a step S118 wherein the flag F2 is set at 1 (F2 ⁇ 1).
- the program proceeds to a step S122 wherein it is judged whether a flag FS is 1 or not.
- the flag FS is determined from a flow chart shown in FIG. 4.
- the program proceeds to the step S109 wherein the compressor 14 is turned on.
- the flag F1 is set at 1 (F1 ⁇ 1).
- the program proceeds to a step S120 wherein the compressor 14 is turned off.
- a step S202 it is judged whether the flag FS is 1 or not.
- the program proceeds to a step S204 wherein it is judged whether a time T1 becomes larger than the predetermined time TS or not.
- the program proceeds to a step S206 wherein the time TS set at 0 (FS ⁇ 0).
- the program proceeds to a step S208 wherein the time T1 is incremented by 1 (T1 ⁇ T1+1).
- FS is not 1 (FS ⁇ 1)
- the program proceeds to a step S210 wherein it is judged whether the start of the shifting was determined.
- the program proceeds to a step S212 wherein FS is set at 1 (FS ⁇ 1). Following this, the program is returned to the start of the flow chart.
- the flag FS is set at 0 when a predetermined time TS has elapsed from the turning-off of the compressor 14 (corresponding to the steps S202, S204 and S206). Accordingly, in case that the time T0 has elapsed from the turning-off of the compressor 14 and the time TS has elapsed from the judgment of the start of the shifting, the operation of the compressor 14 is restarted. Therefore, it not necessary to provide a sensor for detecting the rotation speed of the turbine shaft of the torque converter for the purpose of the control of the air-conditioner. Accordingly, even if the up-shifting can not be carried out due to the breakage of the automatic transmission, the operation of the compressor 14 can be restarred after the elapse of the predetermined time T0 and TS.
